PCI: imx6: Configure REF_USE_PAD before PHY reset for i.MX95
According to the i.MX95 PCIe PHY Databook, the ref_use_pad signal in the
Common Block Signals section selects the reference clock source connected
to the PHY pads. Per the specification, any change to this input must be
followed by a PHY reset assertion to take effect.
Move the REF_USE_PAD configuration before the PHY reset toggle to comply
with the required initialization sequence.
